Interest-Attention Feedback System for Separating Cognitive Awareness into Different Left and Right Sensor Displays

ABSTRACT

A system for generating simultaneous awareness of two separate sensor stimulation patterns ( 1,5,15,16, 23 L, 23 R, 24 L, 24 R) and implementing interest measurement ( 20,22,7 ) and attention factors modification ( 4,10,17,18 ) in different left and right stimulation patterns in order to suppress stereo vision and binocular rivalry and instead facilitate simultaneous observance of both mental images ( 9 ). The user will be able to use the balance point between left and right image rivalry to maintain awareness of a simultaneous dual vision, audio, and tactile experience. Such a doubling experience can be used to:
         extract information and make decisions on two simultaneously observed world views.   maintain two simultaneous views of different computer screens to increase performance and reduce fatigue.   encourage the fusion of two different simultaneous experiences into an abstract information synthesis instead of the conventional three dimensional world view.   perform measurements on interest an operator has on a left right scene content.

BACKGROUND OF THE INVENTION Prior Art

This invention relates to the generation and maintenance of separate left and right mental displays. Separate left and right mental displays are contrasted and distinctly different from the conventional fused three dimensional stereo display produced during normal operation of the brain processing mechanisms. To train a human user to generate two separate mental displays requires measurement and feedback control of attention factors which make the left mental display more or less interesting than the right display. The purpose of this invention is, 1) to provide a means for presenting two individual data streams to the human user, 2) to train human operators to understand and respond to different, usually non-stereo, input images to the left and right eye, and 3) provide a means for automatic control of said attention factors in order to maintain a simultaneous dual mental images.

Investigation for patents and in the open literature has found no invention, research reports, or products explicitly exploiting the possibility of dual or multiple mental image display generation. The term Dichoptic has been used to identify dual scene input exploitation. However our review of Dichoptic vision systems, details of our findings in this technology will be listed below, has shown that they are specifically designed to provide simultaneous narrow and wide field of view scenes to overcome the resolution limitations of computer displays. This application specifically employs dual eye input to augment and enhance stereo vision by increasing the fovea information density in one eye but does not address the production and maintenance of separate mental display generation.

The term binocular rivalry has also been used to describe a mental effect that causes the brain to generate sequential three dimensional mental scenes based first on input from the right eye and subsequently generating a scene based on information presented to the left eye. The rivalry between the subsequent left and right imagery has been extensively studied. The discovery that the rivalry between the left and right scene can be suppressed thus opening the possibility that two simultaneous rather than sequential visualizations can be generated by the brain has to our knowledge not been addressed and represents a new phenomena the invention proposed in this patent application proposes to develop and exploit.

A patent search has found no invention explicitly designed to implement interest-attention feedback mechanisms for dual plane operation of the human visual system. Related helmet mounted display, optical glasses, periscope devices that allow two independent scenes to be received by the left and right eye abound. This invention does not conflict nor is precluded by such devices since none of them use interest-attention feedback to explicitly generate, maintain, and extract information from two simultaneously perceived fields of view.

U.S. Pat. No. 5,334,991 to Wells et. al. (Aug. 2, 1944) show head mounted mirror arrangements that allow two separate images to be introduced to the left and right eye. Related patent documents showing similar but different mounting configurations are cited as follows.

U.S. PATENT DOCUMENTS 3,760,181 August 1973 Daly et al. 250/332 4,439,157 March 1984 Breglia et al. 434/40 4,457,580 July 1984 Klose 359/221 4,632,501 December 1986 Glynn 359/199 4,636,866 January 1987 Hattori 358/236 4,655,543 April 1987 Montagu 359/214 4,861,125 August 1989 Vaught 359/214 4,902,893 February 1990 Burrer 359/201 5,009,473 April 1991 Hunter et al. 359/214

Although mirror devices for left right eye optical inputs have been patented such devices are designed for stereo image applications. None of them are designed for dual experience operation nor contain the interest-attention feedback connections required to implement such operation.

US patent number US 2009/0225001 A1 issued to Biocca et al. dated Sep. 10, 2009 shows a hybrid system designed to project computer controlled wide field of view into one eye and a second narrow field of view onto a patented dome device. This comes closest to a device that makes explicit use of two separate inputs. In this case the purpose was for the explicit use of increasing the apparent resolution of a fovea view and a peripheral view from two images of differing zoom on the same scene. A small business innovative research grant (SBIR) was discovered using a similar setup designated as a Dichoptic Vision System (DIVS) under contract FA8650-10-M-6068 with performance dates (Apr. 22, 2010 to Jan. 21, 2011) with principle investigator Dale R. Tyczka. Again this system was explicitly designed to allow merging of narrow and wide field of view using two computer controlled cameras however the basic interest-attention feedback mechanism required to facilitate simultaneous appearance of two distinct mental images and sound awareness is not included.

We believe the interest-attention feedback mechanism for teaching and maintaining dual experience operation by the human sensory processing has not been invented or patented simply because the ability of the human operator to achieve and maintain cognitive awareness of two different mental displays has not been previously discovered and no research exists to utilize such effects for beneficial purposes.

Objects and Advantages

The goal of this invention is to exploit the potential ability of a human operator to unlearn stereoscopic optical, audio, and tactile data processing and learn to become aware of, understand, and react to two different stimulation streams simultaneously. This invention will double the cognitive bandwidth of a human computer operator by utilizing one eye per computer screen rather than using two eyes per single screen. It will also allow the merging of two separate input data sources into more abstract synthesis of situational awareness than the three dimensional world presentation conventionally produced by a human operator.

Dual input methods are based upon initial experiments conducted with dual eye display systems at Nascent Technologies Incorporated that were designed to explore the possibility of expanding human cognitive bandwidth by using one eye per computer screen rather than both eyes per single computer screen. During these experiments it was discovered that the human vision system could operate in three distinct nodes.

-   -   Stereo: The Brain develops a single 3D visualization of the         world from visual cues derived from stereo pair images input to         both eye as encountered in normal vision.     -   Binocular Rivalry The brain is stimulated with different images         in each eye. The brain selects one of the eye inputs as the         source of the 3D world visualization while suppressing the         opposite eye stimulation. It then flips back and forth between         image sources and alternatively selects one and then the other         image as the source for visualization.     -   Dual experience: The brain suppresses binocular rivalry and         generates two distinct perceptions that are simultaneously         visible and can act as individual situation displays from which         to retrieve information and direct action.

Our experiments have shown a much more comprehensive mental display separation capability may be exploitable that include optic, audio, and tactile sensors and therefore the term “dual experience” is used to distinguish this more comprehensive phenomena from past utilization of stereo optic processing in the brain.

Experiments conducted at Nascent Systems Inc. discovered that the human vision system can see two distinct and separable scenes simultaneously for extended periods of time and extract information from both scenes without generating the normal single three dimensional view typical of stereo vision or rival stereo vision encountered in binocular rivalry. The two left and right scenes can appear interleaved and or separate as though projected on an angular sphere surrounding the operators head.

The key requirement to maintaining the simultaneous dual scene views is to balance the attention factors that make one scene or the other more interesting and thereby frustrate the brains tendency to select one sensor input set as the basis for a fused three dimensional single experience. Attention factors include but are not limited to

-   -   1) image, audio, or tactile changes in illumination, volume, or         pressure respectively     -   2) image, audio, or tactile changes in content such as color,         texture, or rhythm     -   3 image, audio, or tactile changes in content motion, image         size, or angular aspect.     -   4) Any surprises or unanticipated changes of the above listed         attention factors.

The identification of attention factors and ability to control such factors in both the left and right input sensor set is not enough to assure dual experience display operation. To achieve the effect it is necessary to measure the operator's interest in the left and right scene and adjust the attention factors to balance this interest. Hence a feedback loop must be established between an operator's interest in the left or right scene and the attention characteristics included in the left and right scene in order to counteract and balance interest with attention factors and allow both scenes to appear simultaneously. For example if the left scene becomes more interesting that the right scene then the right scene is more strongly illuminated to counterbalance the interest so both scenes stay visible in the perception of the operator.

Measurement of interest can be achieved in two main ways. Either we measure the detectable interest by involuntary external measurements on symptoms of brain activity or we simply ask the operator to volunteer the indicator of interest by moving a suitable body part such as a hand, foot or head. A measurement apparatus such as a lever, dial, or pressure sensor could be used for this purpose. Examples of involuntary non-intrusive interest measurement devices include but are not limited to,

1) Electro Encephalogram measurements

2) Eye motion measurements

3) Retinal response measurements

Examples of voluntary interest measurement devices include but are not limited to,

1) Hand adjustment of a lever

2) Hand adjustment of a rheostat dial

3) Tilting of the hand to the left or right

4) Hand Adjustment of a computer pointing device

In the above examples the hand could also be replaced by a foot, head, arm or any body part that is voluntarily moved to signal an internal mental state of interest.

The potential benefits and utility of dual experience operation are numerous and a partial list of applications is listed below.

-   -   a) Fatigue reduction: Simultaneous scene awareness and         information extraction by internal mental operation is less         fatiguing than utilizing explicit eye movement between different         scenes.     -   b) Cognitive Bandwidth enhancement: The human operator is able         to maintain, utilize and react to different information         presented to the left and right sensor set without switching to         a synthesized 3D scene and thus avoid the time share overhead of         the current mental processing.     -   c) Alternative Vision Synthesis: We know the Human processing         system can synthesize a 3D stereo representation of the world         from two stereo images. We now know the brain can also         synthesize alternative information presentation displays when         different inputs are presented. Examples for differences in         scene inputs that lead to novel synthesis are:         -   different time sequences         -   left and right views generate 360 degree scene         -   inside/outside views of complex objects         -   synthesis of abstract planar information displays         -   alternatives selection and evaluation     -   d) Attention measurement: We know left and right eye inputs will         be selected by the brain in response to attention queues such as         illumination, scene movement or scene changes, or intrinsic         interest in scene content. The dwell time or switching speed         between left and right eye input measures the attention value to         the operator. Such measurements can be used for design of:         -   man machine interfaces         -   warning messages         -   attention value measurement of scene content design         -   The technology has application in overcoming operator             fatigue.     -   e) Augmented Reality and Image registration: Immediately useful         applications for dual experience input involves the use of live         and synthetically generated scenes into the left and right eye         during, for example Unmanned Arial Vehicle flights.     -   Joy stick feedback to maintain registration between scene queues         then enables augmented reality projection for operator         information display but more importantly real scene information         tagging on a pixel by pixel basis for image automated analysis,         data base creation, target identification and geo-location.

SUMMARY

The invention described in this Patent Application pertains to the separate left-right sensor stimulation delivery systems augmented with connections, adjustments, and control apparatus that close a feedback loop between the measurement of a mental interest state and the display of scene attention factors with the explicit intent to create and maintain a simultaneous dual experiences of two different left and right mental display. The invention, interest measurement feedback to control device to maintain dual experience scene awareness, has sensors for involuntary or control input encoders for voluntary indicators to measure the interest in differing non-stereo left and right scene separately presented to each eye, and uses these measurements to adjust scene attention factors in order to balance and maintain both left and right images simultaneously in the human optical perceptive field. The feedback mechanism increases the attention factors in the scene of least interest while simultaneously decreases the attention factor in the scene of most interest in order to maintain interest attention balance.

Accordingly several objects and advantages of the invention are to provide the user a means to maintain cognitive awareness of two distinct mental images simultaneously and become aware and react to the information content of two rather than a single real world representation available under normal operation, to provide a means for training an operator to maintain awareness of two optical inputs without the rivalry displacement effect, to provide the operator a means to synthesize novel merging of information presented in two separate scenes without the fatigue encountered in rapid sequential scene switching, to provide a means for attention and warning queues at the human reflex level without prior external knowledge, identification, or amplification of points of interest.

DETAILED DESCRIPTION OF OPERATION

The following describes the operation of a voluntary interest-attention feedback system described in FIGS. 1 a to 1 d.

1) Setup mirrors (6) set 90 degrees to each other in an oval configuration so that the oval fits against the nose (11) on the left and right side.

2) Provide a flexible membrane (12,13) to fit against the face/nose to eliminate light from sources other than the left or right reflected view.

3) provide a mirror mount (25) to stabilize the mirrors against the face

-   -   3.1) attached to a table mounted stand that one moves ones head         against     -   3.2) or alternatively attached to a head band or helmet

4) Set up a right and left scene in a dark room. Scenes could include but not limited to a live person, a picture, or a screen image mounted on the left and right side of the operator. The ambient light should be dark enough so that the primary illumination intensity is determined by the light sources (2,3) or the single light source (10).

5) Set up two illuminating spot lights (2,3) FIG. 1 a.

-   -   5.1) a single light source (10) in front of the operator can be         used as a single light source for both the left and right scene.

6) Set up an intensity controller (4) that allows one light intensity to be increased while the second is decreased

7) Use one hand (7) to on the controller rheostat knob to adjust the intensity to balance the attention so that both images appear as flat interleaved visuals

-   -   7.1) moving a light source (10) left and right will also         increase the illumination on one while decreasing the         illumination on the opposite scene.     -   7.2) any body part such as a foot, finger or head can be used as         an alternative to the hand interface shown in FIGS. 1 a and 1 b.

8) Maintain the Dual image effect by adjusting the two intensities with one hand. This requires moving the light or control dial back and forth in order to maintain a dual experience visual effect. The operator will notice a tendency for one or the other scene to dominate. This tendency is counteracted by adjusting the attention factor (illumination) to maintain the balance between left and right eye dominance.

9) Depending upon the application various information output mechanisms are employed.

-   -   For Interest measurement applications the control dial position,         or light source position, is noted. The closer the light source         is to a scene at dual experience equilibrium the lower the         interest in that scene.     -   For dual experience information extraction the operator can         output verbal responses or use the second hand to record data of         interest in recording devices such as a mouse, key pad or simply         writing pad.     -   For abstract data fusion the operator will allow a new         appearance to emerge while maintaining attention balance to         avoid the dominant emergence of the left or the right scene.         Abstract data fusion implies the operator experiences a scene         that presents the result of a mental calculation based upon the         data content of the right and left stimulation but not a direct         representation of either the scenes or its three dimensional         stereo fusion achieved during normal sight.

FIG. 2—Additional Embodiment

In FIG. 2 the entire setup is automated using two communicating computers to generate the left and right view. A mouse controls a scene intensity adjustment program with a suitable body part. The mirror setup is replaced with two scene display devices (15,16) controlled by two computer programs. Otherwise the operation is the same as described above. The operator uses mouse, joystick, or other suitable computer input device to indicate interest preference in the left and right scene. By controlling the position of this input device the operator controls an attention factor adjustment program which balances the attention factors of each scene to maintain the simultaneous dual experience view of both scenes. Actual scene content generation and information extraction applications are not defined in this invention. Once a dual experience mental image is maintained the operator can extract data from either scene by point and click or other suitable computer control device without reverting to stereo or single image mental presentation. This may also be setup with a single computer or mobile device capable of producing two scenes.

FIG. 3—Embodiment with Automated Attention Measurement Device

In FIG. 3 the voluntary hand feedback of scene interest is replaced with an external attention factor measurement device. In FIG. 3 scalp mounted EEG pickups (22) are shown to measure brain activity that signal the left and right scene interest and specific attention factors in these scenes. A multi-input analysis program automatically adjusts scene attention factors in order to maintain dual plane visualization. When properly programmed and trained the operator will see a steady dual eye display and can proceed with dual plane information extraction or other operational applications. In this setup the dual plane balance is maintained by external measurement and no voluntary body motion is required. Training sessions of both the EEG interpretation program and the operator are usually required. These training techniques have been developed for EEG control applications and are commercially available. Their utilization for balancing dual experience perception of two scenes is new. The invention is not limited to EEG as a measure of left right scene attention. Alternative measurement devices employing eye tracking, pupil dilation, and facial expression indicators can be employed to measure scene attention and as a basis for calculating attention balancing adjustments.

FIG. 4—Embodiment with Additional Audio and Tactile Stimulation Devices

In addition to visual scene separation discussed in FIGS. 1,2, and 3 the dual experience effect setup is augmented with a left (23L,24L) and right (23R,24R) audio and tactile sensor stimulation set as shown in FIG. 4. The computer system in this embodiment responds to the hand signal provided by the operator indicating attention shift toward the left or right scene. The left and right scene is not generated from visual stimulation only, but also includes left and right separated audio and tactile stimulation. As an example, the attention factor adjustment program can adjust the sound amplitude into the operators left/right ear to balance attention factors using sound stimulation. Similarly increase touch stimulation amplitude can be used to arouse interest and thereby balance attention between the left and right mental images. Coordinated sound will appear to be coming from visual features located in the left/right experience field. The addition of audio and tactile stimulation provides a means for separating a multimedia experience into simultaneous left and right appearances.

Though only a single control device (20) is shown in FIG. 4 finger switches or appropriate interfaces to other body parts can be used to allow individual control of interest whether they adjust attention factors in the optic, tactile, or audio domain. Specifically sound level increase/decrease while maintaining constant optical stimulation has been found to be one adjustment combination that can be effectively used to balance dual experience presentation to the operator. Combinations of control and stimulation adjustments for the three sensation types called out as the multimedia sensor set lead to left/right times optic/audio/touch control times optic/audio/touch attention adjustment combinations for a total of 2×3×3 possibilities. FIG. 4 is a template for all eighteen possible combinations each of which can be used to balance attention between left and right experiences and maintain simultaneous cognitive awareness in both experiences.
